3 essential steps to
choosing the right water pump.
AQUALINE TM pumps are designed for professional use to meet the particular requirements of each worksite, from transferring clean water to more exacting
requirements.
All SDMO ® pumps are self-priming: there is an anti-return valve to fill the intake system by pumping the air through.
NB: the pump must be primed before it is started.
1 Assess the nature of the water 3 Determine the flow
or fluid to be pumped
to choose the right output
Since all liquids needing pumping do not share the same characteristics,
SDMO ® water pumps are designed for multiple purposes depending on:
Water quality
Clean/nearly clean water or dirty water
The AQUALINE TM INTENS range has 2 models, depending on the quality of
the water to be pumped.
- The ST model, specially designed for clear water, is recommended for
applications such as pisciculture, pumping out swimming pools, etc.
- The TR model is specially designed for pumping dirty water, in particular
muddy trenches, excavations, sediment, etc.
The flow corresponds to the maximum quantity of water that can be extracted
at a given height. It is determined by checking the height of elevation in
metres on the curve. The flow in L/min may then be deduced. The height of
elevation determines the available pressure.
This is divided by 10 to obtain the pressure in bar. If this pressure is not
enough, a more powerful model should be selected.
The flow and the discharge height are the main criteria used in selecting
your water pump.

Special fluids, very dirty water and high pressure
There are 3 models of AQUALINE TM SPECIALIST for specific applications.
- The HP 2.26 H is designed for effectively cleaning floors, terraces, agricultural
or worksite plant. It is also invaluable for first line fire-fighting.
- The XC 2.34 H is recommended for agricultural use, for pumping liquid
manure and for handling salt water.
- The XT 3.78 H and TRASH 4 are designed for pumping very dirty water,
for extreme, intensive use, and can handle solid particles from 20 to 30 mm.

Silicon carbide: higher abrasion resistance, lasts longer, low maintenance.
Graphite cast iron: harder, more resistant, too particulate abrasion when taking in water
The flow and pressure equired depending on the head losses.
2 Calculate the height
of the elevation required
The elevation is more or less important depending on the configuration
of the installation or the application (pumping out, sprinkling, irrigation,
draining, washing). It is calculated from:
Typical application
Performance curve
The suction height
This is the difference in height between the level of the water to be
pumped and the axle of the pump. The laws of physics dictate that this
cannot exceed 8m.
The discharge height
This is the difference in height between the axle of the pump and the
highest point of the network.
The head loss
This is the resistance encountered by the water in the pipes. It is calculated
according to the length, diameter and quality of the pipes, their shapes
and the number of accessories (for general cases, we take 20%).
